In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a schematic flow chart illustrating an implementation of a method for controlling a fan according to an embodiment of the present invention, which is described in detail below.
In the step, the current water temperature of the engine and the target water temperature of the current state of the engine are obtained;
calculating the difference between the current water temperature and the target water temperature;
and taking the difference as an input variable, obtaining the required rotating speed of the electromagnetic silicone oil fan through a PID control algorithm, and sending the required rotating speed to the electromagnetic silicone oil fan, so that the electromagnetic silicone oil fan runs at the required rotating speed, and the temperature of the whole vehicle is reduced.
It should be noted that the required rotation speed of the electromagnetic silicone oil fan is changed in real time according to the water temperature of the engine, and therefore the required rotation speed is a variable.
And 102, when the air conditioner pressure is greater than a first preset pressure, increasing the current rotating speed of the electromagnetic silicone oil fan according to a preset speed increasing mode.
In an embodiment, the preset speed-up mode may be speed-up according to a speed-up coefficient requested by the air conditioner controller, or speed-up according to a preset speed-up coefficient, and this step may include:
when the air conditioner pressure is greater than a first preset pressure, increasing the current rotating speed of the electromagnetic silicone oil fan according to a received first speed increasing request sent by an air conditioner controller, wherein the first speed increasing request comprises a coefficient adopted for increasing the current rotating speed of the electromagnetic silicone oil fan;
or when the air conditioner pressure is greater than the first preset pressure, the current rotating speed of the electromagnetic silicone oil fan is increased according to a preset speed increasing coefficient by a received second speed increasing request sent by the air conditioner controller.
Optionally, the coefficient for increasing the current rotation speed of the electromagnetic silicone oil fan and the preset speed increasing coefficient are not limited in this embodiment, and may be set according to actual requirements. For example, it may be 1.1, 1.2, 1.5, etc.
In an embodiment, this step may be preceded by:
monitoring whether a speed-up request sent by an air conditioner controller is received, wherein the speed-up request comprises a first speed-up request or a second speed-up request, and the speed-up request is generated when the air conditioner controller is higher than a first preset pressure.
When a speed-up request sent by the air conditioner controller is received, the current rotating speed of the electromagnetic silicone oil fan after speed-up can be obtained by multiplying the coefficient included in the first speed-up request by the required rotating speed, or the current rotating speed of the electromagnetic silicone oil fan after speed-up can be obtained by multiplying the preset speed-up coefficient by the required rotating speed according to the second speed-up request.
Optionally, when a speed-up request sent by the air conditioner controller is received, it is indicated that the air conditioner pressure is relatively high, and the air conditioner pressure needs to be reduced by increasing the rotation speed of the electromagnetic silicone oil fan. Namely, when the air conditioning pressure is not greater than a first preset pressure, the electromagnetic silicone oil fan is controlled to operate at the required rotating speed.
Optionally, in this embodiment, a value of the first preset pressure is not limited, and the value of the first preset pressure may be set according to an actual requirement, for example, the first preset pressure may be 1.7MPa, 1.9MPa, or 2 MPa.
In an embodiment, this step may be followed by:
detecting the current air conditioner pressure and the current rotating speed of the electromagnetic silicone oil fan after the speed is increased;
after the speed is increased, when the current rotating speed of the electromagnetic silicone oil fan does not reach the highest allowable rotating speed and the current air-conditioning pressure is greater than the second preset pressure, skipping to a step of increasing the current rotating speed of the electromagnetic silicone oil fan according to a preset speed increasing mode.
Optionally, the second preset pressure is less than or equal to the first preset pressure. Optionally, in this embodiment, a value of the second preset pressure value is not limited, and a value of the second preset pressure value may be set according to an actual requirement, for example, the second preset pressure value may be 1.5MPa, 1.3MPa, or 1 MPa.
When the current rotating speed of the electromagnetic silicone oil fan is not the highest allowable rotating speed of the electromagnetic silicone oil fan after the speed is increased, the air-conditioning pressure is continuously monitored when the electromagnetic silicone oil fan operates at the current rotating speed of the electromagnetic silicone oil fan after the speed is increased, so that the current rotating speed of the electromagnetic silicone oil fan after the speed is increased is adjusted according to the air-conditioning pressure.
It should be noted that, when the current rotating speed of the electromagnetic silicone oil fan does not reach the maximum allowable rotating speed of the electromagnetic silicone oil fan after the speed is increased and the current air-conditioning pressure is not greater than the second preset pressure, the electromagnetic silicone oil fan is controlled to operate at the current rotating speed of the electromagnetic silicone oil fan after the speed is increased.
And when the current rotating speed of the electromagnetic silicone oil fan is the highest allowable rotating speed of the electromagnetic silicone oil fan after the speed is increased and the current air-conditioning pressure is greater than a second preset pressure, executing the step 103.
And 103, controlling the condenser fan to be started when the current rotating speed of the electromagnetic silicone oil fan reaches the highest allowable rotating speed of the electromagnetic silicone oil fan after the speed is increased and the current air-conditioning pressure is greater than a second preset pressure.
In this embodiment, through electromagnetism silicon oil fan and independent condenser fan coordinated operation, when the rotational speed of electromagnetism silicon oil fan reached the maximum allowable rotational speed, further reduced whole car temperature through the condenser fan to can further improve the cooling effect, and can effectively utilize the energy consumption of whole car fan system, improve the energy consumption utilization ratio, rather than open the condenser fan all the time and lead to the energy consumption too high.
In an embodiment, when the current rotating speed of the electromagnetic silicone oil fan reaches the maximum allowable rotating speed of the electromagnetic silicone oil fan after the speed is increased and the current air-conditioning pressure is not greater than a second preset pressure, the electromagnetic silicone oil fan is controlled to operate at the current rotating speed of the electromagnetic silicone oil fan after the speed is increased.
And 104, in the process of starting the condenser fan, controlling the condenser fan to be closed when the current air conditioner pressure is detected to be not more than a second preset pressure.
After the condenser fan is turned on, the condenser fan needs to be controlled to be kept in an on state or off according to the air conditioner pressure, so that the energy in the vehicle can be effectively utilized.
In an embodiment, after step 103 and before this step, the method may further include:
detecting whether the current air conditioner pressure is greater than a second preset pressure or not;
when the current air conditioner pressure is detected to be greater than the second preset pressure, the opening state of the condenser fan is kept, and the electromagnetic silicone oil fan is kept to operate at the current rotating speed of the electromagnetic silicone oil fan after the speed is increased, so that the electromagnetic silicone oil fan and the condenser fan are cooled together, and the cooling efficiency is improved.
When the current air-conditioning pressure is detected to be not greater than the second preset pressure, the current air-conditioning pressure is suitable, and the condenser fan can be turned off.
According to the control method of the fan, the required rotating speed of the electromagnetic silicone oil fan is determined, when the air conditioning pressure is larger than the first preset pressure, the current rotating speed of the electromagnetic silicone oil fan is increased according to a preset speed increasing mode, when the current rotating speed of the electromagnetic silicone oil fan reaches the highest allowable rotating speed of the electromagnetic silicone oil fan after speed increasing, and when the current air conditioning pressure is larger than the second preset pressure, the condenser fan is controlled to be started, so that the temperature of the whole vehicle can be further reduced through the condenser fan, the cooling effect is further improved, and in the process of starting the condenser fan, when the current air conditioning pressure is detected to be not larger than the second preset pressure, the condenser fan is controlled to be stopped, so that the energy consumption of a fan system of the whole vehicle can be effectively utilized, and the energy consumption utilization rate is improved.
Fig. 2 is a detailed embodiment of a method for controlling a fan according to an embodiment of the present invention, which is described in detail below.

PID controls the required rotating speed N of the electromagnetic silicone oil fan to be output, the required rotating speed is sent to an electromagnetic silicone oil fan controller, and the electromagnetic silicone oil fan is controlled to operate at the required rotating speed;
thirdly, the air conditioner controller monitors the air conditioner pressure, and if the air conditioner pressure is less than 1.7MPa, the air conditioner controller does not send a speed-up request;
if the air conditioner pressure is monitored to be not less than 1.7MPa, the air conditioner controller sends a first speed-up request, and the first speed-up request is that the rotating speed N of the electromagnetic silicone oil fan requested by the engine is multiplied by 1.1 times so as to try to reduce the air conditioner pressure;
the fan controller monitors whether a first speed-up request is received, if the first speed-up request is not received, the electromagnetic silicone oil fan rotating speed N of the engine water temperature request is directly executed, if the first speed-up request is received, the electromagnetic silicone oil fan rotating speed N of the engine water temperature request is multiplied by 1.1 times, and 1.1 × N is recorded as the current rotating speed of the electromagnetic silicone oil fan; the current rotating speed of the electromagnetic silicone oil fan is a variable, and because the PID controlled fan is controlled in real time according to the temperature difference of the engine, N is changed at any moment, so 1.1 × N is also changed at any moment;
judging whether the current rotating speed of the electromagnetic silicone oil fan is the maximum allowable rotating speed of the electromagnetic silicone oil fan by the controller;
if the maximum allowable rotating speed of the electromagnetic silicone oil fan is not higher than the maximum allowable rotating speed, continuously detecting whether the air conditioner pressure is improved, namely whether the air conditioner pressure is lower than 1.5MPa, and if the air conditioner pressure is not lower than 1.5MPa, continuously sending a first speed-up request, namely sending a request that the rotating speed of the electromagnetic silicone oil fan is 1.1 × "the current rotating speed of the electromagnetic silicone oil fan";
if the maximum allowable rotating speed of the electromagnetic silicone oil fan is not the maximum allowable rotating speed, and the air conditioner pressure is judged to be 1.5MPa less, the controller requests the electromagnetic silicone oil fan to execute the current rotating speed;
ninthly, if the rotating speed of the current electromagnetic silicone oil fan is judged to be the maximum allowable rotating speed and the current air-conditioning pressure is less than 1.5MPa, the controller requests the electromagnetic silicone oil fan to execute the current rotating speed; if the rotating speed of the current electromagnetic silicone oil fan is determined to be the maximum allowable rotating speed and the current air-conditioning pressure is not less than 1.5MPa, the controller requests the condenser fan to be started;
after the condenser fan at the red (R) is started, continuously judging whether the current air-conditioning pressure is less than 1.5MPa, if so, closing the condenser fan, otherwise, keeping the condenser fan on, and simultaneously, continuously requesting the electromagnetic silicone oil fan to be started by the controller;
it should be emphasized that, in the above entire control process, the temperature difference of the engine and the PID control of the electromagnetic silicone oil fan are always kept, the required rotation speed N of the electromagnetic silicone oil fan obtained by the PID control is a variable and changes constantly, and the fan rotation speed executed by the electromagnetic silicone oil fan is defined as a variable "current rotation speed", and since the condenser fan needs to iterate continuously, the rotation speed of the electromagnetic silicone oil fan needs to be redefined as the "current rotation speed".
Through confirming the demand rotational speed of electromagnetism silicon oil fan, when air conditioning pressure is greater than first preset pressure, according to the mode of predetermineeing the speed-up, improve the current rotational speed of electromagnetism silicon oil fan, the current rotational speed of electromagnetism silicon oil fan reaches the highest rotational speed that allows of electromagnetism silicon oil fan after the speed-up, and when current air conditioning pressure is greater than second preset pressure, control condenser fan and open, thereby can further reduce whole car temperature through condenser fan, further improve the cooling effect, and at condenser fan opening in-process, when detecting that current air conditioning pressure is not more than second preset pressure, control condenser fan is closed, thereby can effectively utilize the energy consumption of whole car fan system, improve the energy consumption utilization ratio.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
